Jackson was set to compete on the UFC 153 card for what has been discussed as his last fight in the Octagon, but now it appears that plan will be delayed.

UFC officials made no indication if Teixeira would remain on the card against a new opponent or face a replacement fighter on short notice.

UFC 153 has already undergone radical changes over the last few weeks with Vitor Belfort and Alan Belcher both falling off the card, as well as Erik Koch suffering an injury forcing him out of his scheduled fight with Jose Aldo.
